Different use of quotes on macros?

Hi all, I’ve been using SC for a year or so but new to actually posting on the forum! So, apologies if this in the wrong place.

Can anyone help me out with the difference between curly and straight quote use in macros?

For example I’ve been trying to use;

sc_field_disabled_record(“field_1=false”);

But discovered it only works by using;

sc_field_disabled_record(“field_1=false");

All other macros I’ve come across appear to use straight quotes as I would expect. Can anyone explain the different use to me please?

The first one should be straight quotes!
